I'm soon to be in contact with a company specializing in CDC (Composite Diamond Coatings). Diamond, as we all know, is the golden standard of coatings seeing as it is perfectly bioinert and almost completely indestructible. The average coating thickness is 0.0508mm, with low error tolerance.
Topics I will bring up in talks:
* Maximum temperature reached in coating process, so I can guarantee no loss of magnetism.
* minimum order size
* minimum part size
* smoothness of coating. (Don't want to be cutting yourself internally for years on sharp diamond.)
Please feel free to include any thoughts, suggestions, or other tidbits. If the quotes go well I was thinking of organizing this as a group buy as diamond coating can't be the cheapest thing on the market.
Already hit a brick in the road. The company posted that:
Please note that our curing temperature may range from ambient to 750°F, and nominally 550°F - 750°F.
While this throws a monkey wrench in the works, I'm going to continue to pursue this route of questioning, in case they would be able to do any coating at a lower temperature. (Will also be researching how to re-magnetize neodymium magnets)
While remagnetizing a neodymium magnet is a simple as one, two, 9400$ equipment, I will also inquire K&J magnets, as well as other magnet retailers if I can ship them back to have them remagnetized.
